Abstract
Pathological changes in brain electrical activity over time caused by for example growth of a lesion are detected by producing a brain electrical activity map such as a statistical probability map, and then selecting a template or mask surrounding a suspect area, summating values of the map within the template area to form an aggregate statistical feature, and then plotting the feature over a period of time, e.g. several weeks, to form a trend plot characteristic of brain electrical activity changes.
